Sample Indiana CDL Test Questions - General Knowledge

Question 1

When fighting an engine-compartment fire, you should fully open the hood before using the extinguisher.

  1. A True
  2. B False

Correct answer: B – False

Turn off the engine as soon as possible, but avoid opening the hood if you can. Direct foam through the louvers or radiator or from underneath the vehicle. Opening the hood is not the recommended first step for reaching the base of an engine-compartment fire.

Question 2

What is the primary safety reason for inspecting a commercial vehicle?

  1. A To complete the trip paperwork
  2. B To find defects that could cause a breakdown or crash
  3. C To check only the exterior lights
  4. D To confirm the tires are overinflated

Correct answer: B – To find defects that could cause a breakdown or crash

Safety is the most important reason for inspecting a commercial vehicle. Finding a defect before driving can prevent a mechanical breakdown or a crash that endangers the driver and other road users. Inspections should cover all required components rather than focusing only on lights or tires.

Question 3

Hazardous materials are divided into how many hazard classes for transportation?

  1. A 3
  2. B 6
  3. C 9
  4. D 12

Correct answer: C – 9

Federal hazardous-material regulations establish nine numbered hazard classes, and some classes are divided further. The classes cover explosives, gases, flammable liquids, flammable solids, oxidizers and organic peroxides, toxic and infectious substances, radioactive material, corrosives, and miscellaneous hazardous materials. Drivers use these classifications when checking shipping papers, labels, and placards.

Question 4

What is one important characteristic of a convex mirror?

  1. A It shows a wider area than a flat mirror
  2. B It makes objects appear closer than they are
  3. C It makes objects appear larger than they are
  4. D It eliminates every blind spot

Correct answer: A – It shows a wider area than a flat mirror

Convex mirrors provide a wider field of view than flat mirrors, helping drivers observe more of the area beside and behind a large vehicle. However, objects appear smaller and farther away than they actually are. Drivers must account for this distortion when judging another vehicle’s distance.

Question 5

Which description best defines controlled braking?

  1. A Using the brakes only on a vehicle without ABS
  2. B Braking as firmly as possible without locking the wheels
  3. C Locking the wheels, releasing the brakes, and applying them again
  4. D Holding the brakes down after all wheels lock

Correct answer: B – Braking as firmly as possible without locking the wheels

During controlled braking, apply the brakes as hard as possible without locking the wheels. Keep steering movements small. If the wheels lock or a larger steering correction becomes necessary, release the brakes and reapply them as soon as possible.

Question 6

Which checks apply to a sliding fifth wheel during an inspection?

  1. A Check the slide for damage or missing parts and, if air-powered, for leaks
  2. B Verify that all locking pins are present and locked in place
  3. C Confirm that its position provides clearance during turns
  4. D All of these

Correct answer: D – All of these

During Indiana’s combination-vehicle inspection, examine the sliding fifth wheel for damaged or missing parts and air leaks if it is air-powered. Confirm that all locking pins are present and secured. The fifth wheel must also be positioned so the tractor frame and cab have adequate clearance from the landing gear and trailer during turns.
